Can anyone promote my extension on 50/50 profit sharing basis? (chromewebstore.google.com)

I earn by selling premium package from this extension Digital Shield, As user base is very low its about 10 or 12 sell i get per month, If anyone promote the extension so increase sell i will share 50 % of the amount.
